In US. Pat No. 3,348,874, I disclosed a combination boattentcamper-trailer apparatus which utilized a boat in an overturned positionon a trailer to cover a tent camper mounted on the trailer. The tentcamper was limited in its utility since it was a part of the trailer andcould therefore be set up for use only in the location of the trailer.

SUMMARY OF THE INVENTION The present invention is an improvement overthe apparatus of said US. Pat. No. 3,348,874 in that the tent-camper isa self-contained unit which is detachably or removably mounted on atrailer, and which is also capable of floating, so that the tent campermay be removed from the trailer and towed or otherwise moved in a lake,river or other body of water to a point remote from the location of thetrailer, so that the tent camper may be set up and used at an otherwiseinaccessible place. The tent camper and the boat may also be returned tothe trailer and repositioned thereon for movement together over thehighway or other roads.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, the letter Adesignates generally the apparatus of this invention which includes atrailer T, a tentcamper C, and a boat B. Briefly, the apparatus A is soconstructed that the camper C may be removably mounted on the trailer Tso that the boat 8 may also be removably mounted on the trailer T in anoverturned or upsidedown position, covering the camper C fortransportation over the highways or roads R (FIG. 1). In the preferredform of the invention, the tent-camper C is capable of floating (FIG. 4)so that when the boat and the camper have been removed, both the boat 8and the camper C may be floated to a location which is remote from thetrailer launching point. This makes it possible to use the boat and thecamper together at a point remote from and in an otherwise inaccessibleplace, insofar as the trailer T is concerned.

Considering the invention more in detail, the trailer T has a frame Fwhich preferably includes two side frame members 20 which are disposedsubstantially parallel to each other. The frame F has a tent campersupport surface 21 formed on each side frame member 20 for receiving thelower portion of the tent camper C, as will be more fully explainedhereinafter. The trailer frame F also includes a boat support surface 23on each side frame member 20, which preferably includes a strip thereonof rubber or other resilient material for contact with an edge of theboat B when in the overturned position (FIG. 9).

A side portion of wall 24 which extends upwardly from each surface 21serves to confine the camper C laterally when the camper C is disposedon the support surfaces 21. An intermediate substantially horizontalportion 25 connects each side portion 24 to a vertical portion 26 whichin turn is connected to each support surface 23 for each of the sidemembers 20.

The rearward ends of the side frame members 20 are open and are notpermanently closed so as to permit the positioning of the camper C on,and removal from, the surfaces 21, as will be more fully explained.Suitable laterally extending frame members 27 are disposed underneaththe side frame members 20 for rigidly connecting the frame members 20together without interference with the surfaces 21.

Since the camper C is normally shorter in length than the boat B, thetrailer frame F may also include interconnecting spacer members 28 whichform a compartment forwardly of the surfaces 21, which is closed by aboard 29 of plywood or other similar material. Such compartment may beused for storage. The forward part of the trailer frame F is preferablyprovided with front members 30 having an inverted U-shaped tonguesupport member 31 welded or otherwise secured therebelow (FIG. 14). Atongue 32 (FIG. 13 and 14) is mounted in the tongue support 31 by one ormore pins 33 and 34. The pin 33 is preferably a removable pin whichextends through suitable holes in the side of the support member 31. Acotter pin 33a may be removably positioned through an opening at theouter extremity of the pin 33 so that upon removal of the cotter key 330from the removable pin 33, such pin 33 may be removed from the tongue 32and from the support 31 therewith. When the pin 33 is thus removed, thetongue 32 is pivotally supported on the pin 34 which also extendsthrough the tongue 32 and the sides of the support 31. Such pin 34 mayalso be removed when it is desired to completely remove the tongue 32from the frame F for shipping or other purposes. When the pin 33 isremoved and the pivoting of the tongue occurs about the pivot pin 34, anincreased angle of inclination of the trailer T with respect to avehicle pulling same may be accomplished (FIG. 4).

The tongue 34 extends forwardly with respect to the frame F a sufficientdistance to receive a vertical post 37, which is preferably removablysecured to the tongue 32 by one or more retaining bolts or screws 370which extend through suitable openings in downwardly extending tabs 37band the tongue 32. The vertical post 37 is supported by an inclinedbrace 38 which is releasably attached to an uprig t adjustable trailerhitch mounting structure 39 by a removable bolt or screw 38a. Thebracket 39 has a .plurality of holes therethrough for receiving a pairof bolts 40a on a trailer hitch 40 so that the height of the trailerhitch 40 may be adjusted to accommodate the elevation of the ballportion 40b of the trailer hitch which is connected to the automobile,truck or other vehicle pulling the trailer T. The trailer hitch 40 maybe of any conventional type, the details of which form no part of thisinvention. At the upper end of the vertical post 30, a winch 42 having aconventional handle crank mechanism 42a therewith is mounted for thewinding and unwinding of a cable 42b (FIGS. 2 and 4) relative thereto.As will be explained, the cable 42b is adapted to be releasably attachedto the boat B for guiding and controlling same during the removal andrepositioning of the boat B with respect to the trailer T. Also, suchcable 42b may be used for controlling the removal and repositioning ofthe tentcamper C on the trailer T, as will be more fully explained.

The trailer T also includes a set of wheels W which are preferablysecured together as a unit and which may be removed from the frame F andalso secured to such frame F as a unit. Thus, as shown in FIG. 12, thewheel assembly W includes a pair of wheels 43 which are connectedtogether with an axle 44, such axle 44 having a pair of leaf springs 45secured thereto, and to which are attached connecting plates 46. Theconnecting plates 46 have holes 460 drilled therein which are adapted tobe aligned with corresponding holes 25a in the substantially horizontalframe portion 25, and through which retaining bolts (not shown) areadapted to be positioned to thereby secure the set of wheels W below theframe F. By removing the bolts making the connection of the wheels W tothe frame F, the trailer T may be more readily shipped. The wheels 43may also be removed from the rest of the wheel assembly W for shippingor other purposes.

In some instances, it may be desirable to detach the trailer hitch 40from the car or other pulling vehicle, in which case, it is desirable tosupport the trailer T in a substantially horizontal position. Toaccomplish such support, the trailer T may be provided with pivotallymounted rear support legs 50 which are pivoted at pivot pins 51 to theframe F (FIGS. l-3). A forward support post 52 is slidably mounted in aretaining bracket 53 on the post 37. A holding setscrew 530 may beinserted through the bracket 53 into engagement with the sup port post52 so as to hold same in the raised position of FIG. 1 when the trailerT is in transit. By releasing such setscrew 530, the post 52 may becaused to drop downwardly until it engages the ground G (FIG. 2), withthe trailer T in a substantially horizontal position. The setscrew 53amay then be reengaged in contact with the post 52 to prevent furtherrelative movement between the post 52 and the trailer frame F.

The tent-camper C includes a housing 60 which is essentially square orrectangular in shape, although it may have a sharp prow shape 60a (shownin dotted lines in FIG. to facilitate the movement thereof in the waterwhen towing same. The housing 60 is watertight and waterproof so that itwill float together with the contents therein. Suitable runner strips 61of wood, metal or other suitable material are provided at the lowerouter edges of the bottom of the housing 60 for sliding engagement onthe support surfaces 21 of the trailer T. Such runners 61 also serve tokeep the lower portion of the housing 60 off the ground when the camperC is used directly on the ground (FIG. 6).

The construction of the camper C may vary, but preferably, the camper Chas one or more covers 62 which are hinged at 62a to the housing 60 soas to swing from a closed position over the housing 60 (FIGS. 2 and 4)to an open position, wherein such covers 62 serve as the deck or floorportion of the camper C (FIGS. 5 and 6).

When the hinged covers are in the open position, they are maintained ina horizontal position by suitable legs, an example of which isillustrated in FIG. 8. Thus, each cover 62 preferably has a threadedsocket 63 secured thereto for receiving one or more legs 64 and 65. Whenthe camper C is used directly on the ground as illustrated in FIG. 6 theshort legs 64 are utilized together with a base 66 which is preferablyconnected thereto with a threaded nipple 64a. When the camper C is setup in the position for use shown in FIG. 3 while still on the trailer T,the longer legs 65 are used together with the base 66 for each of suchlegs 65. When the camper C is mounted on the bed of a pick up truck(FIG. 7), both of the legs 64 and 65 are connected together with athreaded nipple 64a, and with the base 66 mounted at the lower end ofthe legs 65. It will be appreciated that the upper end of the particularleg which is used is threaded into one of the threaded sockets 63, andnormally, two legs of suitable height are used for supporting each ofthe covers 62 in the open position.

To facilitate the handling of the camper C with respect to the trailerT, a forward handle or eye 67 is mounted at the forward end of thehousing 60 so that it may be releasably engaged by a suitable hook orclamp (not shown) on the end of the cable 42b. For towing the camper Cin the water by boat B, a pair of handles or eyes 68 are mounted at therear end of the housing 60 so that a rope or other suitable connectorcable 680 may be attached from the boat B to such handles 68.

The camper C is adapted to slide on the support surfaces 21 and it isretained laterally by the side portions or walls 24. The camper C isconfined at the front end of the trailer T by the laterally extendingbrace 28 at the forward end';of trailer T. The camper C is retained atthe rear end of the trailer T by a releasable and removable retainingbar 70 (FIG. 12) which is adapted to slide into the groove provided bythe substantially horizontal side portions 25, the upright portions 26and the support surfaces 23. When the retaining bar 70 is in suchgrooves of the trailer frame F, it closes the rear end of the frame F soas to prevent any rearward movement of the camper C. The retainer bar 70is locked relative to the frame F by retaining setscrews 71 which arethreaded into threaded pipes 72 welded to the rear part of thehorizontal portions 25 (FIG. 12). The setscrews 71 are thus threadedupwardly through the threaded pipes 72 and engage the lower surface ofthe bar 70. If desired, a threaded socket (not shown) may be provided inthe bar 70, into which the retaining screws 71 enter for holding theretainer bar in the end position within the trailer frame F.

For pivotally mounting the rear portion of the boat B to the trailer T,the transom 75 of the boat B is provided with two specially mountedpivot pin units 76. Each pivot pin unit 76 has a frame 760 which isconnected to the transom 75 by one or more retaining bolts 76b. The unit76 has a pivot pin 76c which is formed integrally with the frame orbracket portion 76a and is preferably disposed substantially inalignment with the normally upper edge 75a of the transom 75.

The retainer bar 70 has suitable releasable latch means 80 (FIGS. 11 and12) mounted thereon to releasably latch the hinge pins 76c to thetrailer T. In the form of the invention illustrated in the drawings,each releasable latch means 80 includes a hollow latch portion 80ahaving a substantially U- shaped pivot pin bracket 80b formed orconnected therewith. Each pivot pin bracket 80b extends rearwardly ofthe retainer bar 70 and is adapted to receive a pivot pin 76c. Aslidable latch plate 800 is slidably disposed in the tubular portion80a, and it is urged to its rearward latching position by a spring 80d.Each latch means 80 is secured to the retainer member 70 by means of apair of bolts or fasteners 80c, with one of such fasteners 80e servingto limit the rearward extent of movement of the latch plate 800. Bymanually pushing the latch plate 80c rearwardly, the open portion of thepin bracket 80b is exposed so that the pin 76c may be inserted thereinor removed therefrom to thereby position or remove the boat B relativeto the trailer T.

The particular shape and construction of the boat B may vary, so long asthe boat B is capable of covering the camper C and is also of suchlength as to conveniently fit upon the trailer T. Normally, the boat Bis of substantially the same length as the trailer T and it preferablyis formed with a specially shaped gunwale which includes a gunwalesurface (FIG. 9) which rests in contact with the resilient seal strip23a when the boat B is in the upsidedown or overturned position. Also,an outer lip 91 is formed at the gunwale so as to overhang the outsideedge of the frame F and to thereby provide a closure which preventswater and foreign objects from flying upwardly into the boat B duringthe transit of same on the trailer T. When the boat B is in theupsidedown or overturned position over the camper C (FIG. 1), theforward end of the boat may be tied down by any suitable means, and ifdesired the cable 42b may be used for such purposes by passing samethrough an eye 93 which is welded or otherwise secured to the upper endof the tongue 32 (FIG. 1). The boat B has a suitable eye or connector(not shown) secured to it at its forward end to receive a conventionalbook (not shown) on the cable 42b for such holddown purposes.

In the operation or use of the apparatus A of this invention, the camperC is initially slid or moved longitudinally forwardly on the supportingsurfaces 21 of the trailer T to its location substantially midway overthe wheels 43 (FIG. 2). The retainer bar 70 is then secured to the rearportion of the trailer frame F by the retainer screws 71. Thereafter,the boat B is releasably hinged with its hinge pins 760 to the latchmechanism 80 for each of such pins 760, and is lowered to the upsidedownposition shown in FIG. 1. The forward end of the boat B is then securedin any suitable manner, and the entire apparatus A is then ready fortransportation by pulling same with any type of suitable vehicleconnected to the trailer hitch 40. The boat B provides a streamlinedcover for the camper C during transit. Also, the plywood bottom 29, andthe bottom of the camper C essentially cover the entire lower portion ofthe boat B so as to protect its inside surfaces during transit.

When the trailer apparatus A has thus been transported over a roadway Rto a suitable location for the use of the boat B and the camper C, theboat B is first removed from the trailer T. Although it is preferable topivot the boat about the hinge pins 760 from the substantiallyhorizontal upsidedown position of FIG. 1 to that of FIG. 2 andultimately to an upright position in the water (FIG. 4), the boat B maybe moved off of the trailer T by turning same on its side or byotherwise simply lifting the boat B vertically and moving it laterallyaway from the trailer T. However, when the boat B is relatively heavy,the preferred procedure for removing it is illustrated in FIG. 2 whereinthe cable 42b is attached to the bow or forward portion of the boat B tofacilitate the guiding and lowering of the boat B from the substantiallyvertical position to a substantiaily horizontal position about the hingepins 76c. When the boat B has reached the substantially horizontalupright position, the releasable latches 80 are released by pushing thelatch members 800 forwardly against the springs 80d so that the hingepins 760 can be moved out of the hooks or brackets 80b. Thereafter, theboat B may be moved away from the trailer T, as desired. The end of thecable 42b which is connected to the boat B may be disconnected when theboat reaches its substantially horizontal position, so that the cable42b may be rewound on the winch 42.

If it is then desired to use the camper C on the trailer T as shown inFIG. 3 the camper C is set up in the usual manner so that it assumes theposition shown in FIG. 3.

However, if it is desired to remove the camper C from the trailer T, theretainer bar 70 is removed after first removing the retainer screws 71.Then, the camper C may be slid or moved longitudinally rearwardly withrespect to the frame F. To control the rearward movement of the camperC, particularly when lowering same into a body of water R such asillustrated in FIG. 4, the cable 42b is preferably secured to the hookor eye 67 at the forward end of the camper C.

With the trailer T on the ground G at the edge of the water R, thetongue pin 33 may be removed to place the trailer T at a steeper anglewith respect to the trailer hitch 40 and the vehicle with the trailer T.The camper C may then be slid rearwardly more easily from the trailer Tinto the water R. The boat B may be connected to the rear end of thecamper C by using the line or rope 68a to pull the camper C and alsocontrol same after it gets into the water R. The connection of the cable42b to the hook or eye 67 of the camper C controls the speed of movementof the camper C as it slides into the water. After the camper C is inthe water the cable 42b may be released and rewound on the winch 42.Thereafter, the trailer T may be moved to a storage point while the userof the boat B and the camper C may proceed on the water to any locationdesired which may be remote from the point of launching the boat B andthe camper C. For example, the user of the apparatus A may be afisherman who desires to proceed to an island in a lake, river or otherbody of water. The island would be inaccessible to the trailer T, butwith the floatability of the camper C, the user of this apparatus maypull the camper C to the island and there pull it upon the ground andset it up for use in proximity to the point at which he is also usingthe boat in the water.

After the camper C and the boat B have been used and it is desired toreturn them to the trailer T, the reverse procedure to the launchingsteps is then carried out. Thus, the trailer T is positionedsubstantially as shown in FIG. 4 adjacent the body of water, the cable42b is connected to the eye or hook 67 on the camper C, and the camper Cis pulled longitudinally into the open rear end of the frame F so thatthe lower portion of the camper C slides upwardly on the supportsurfaces 21 of the frame F. The camper C is pulled as far forwardly aspossible and then the cable 42b is detached from the camper C.

The retainer bar 70 is then placed in position on the trailer frame Fand the retainer screws 71 are secured thereto for thereby holding thecamper C in position on the trailer T.

The boat B is then moved into position with its stern adjacent the endof the trailer F to reconnect the hinge pins 760 in the U-shapedbrackets b of the latch means 80. If the pin 33 has been removed forsuch returning operation of the camper C, the trailer T may be tilted toits raised position (FIG. 1) and the tongue 32 may then be rigidlyconnected to the bracket 31 with the pin 33. After the pins 760 havebeen inserted into the brackets 80b, the free end of the cable 42b isconnected to the bow or forward end of the boat B so that it is thenpossible to pivot or swing the boat B upwardly from the substantiallyhorizontal upright position to the upsidedown position. When the boatreaches the substantially vertical position (FIG. 2) the lowering of theboat B then moves by gravity to its overturned or upsidedown positionshown in FIG. 1. The forward end of the boat B is then secured to theframe F and the entire apparatus A may then be moved again over highwaysand roads by pulling same with a vehicle.

It will be appreciated that variations in the apparatus A may be madewithin the scope of this invention. For example, a sheet of plywood,metal, or other material may be secured to the braces 27 between theside support surfaces 21, or therebelow, to serve as a dust cover forthe interior of the boat B when it is in the upsidedown position.

The foregoing disclosure and description of the invention areillustrative and explanatory thereof, and various changes in the size,shape, and materials as well as in the details of the illustratedconstruction may be made without departing from the spirit of theinvention.
